A Review of Energy Consumption in the Acquisition of Bio-Feedstock for Microalgae Biofuel Production
Microalgae biofuel is expected to be an ideal alternative to fossil fuels to mitigate the effects of climate change and the energy crisis. However, the production process of microalgae biofuel is sometimes considered to be energy intensive and uneconomical, which limits its large-scale production. S...
